Quite a lot of the different department stores have their own lingerie ranges and they're a lot nicer than you'd expect. I've gotten some lovely stuff from Next, Debenhams, George at Asda, Marks and Spencers and Peacocks. Their swimwear's quite good as well.

Try primark, that way you will be able to make money and spend.. i'm sure loads a sexy glamour mods go in there for their stuff coz its cheap.

My advise would be to look around, go into sales and pick up as many bargains as you can. I rarely do clothed modelling but I have enough clothes to fill wardrobes up. If I see something which I think will photograph well with a 75% off sticker then its in my basket in a heartbeat. If something costs £10-£20 and you wear it on two or three shoots then its been worth the investment. Also means after you have taken it out of your shoot wardrobe you can just wear it everyday.
